What Oil Pulling Is and How It Is Done

At its simplest, oil pulling means holding a small amount of edible oil in your mouth and swishing it around — pulling and pushing it between your teeth — for a stretch of time, then spitting it out and rinsing. The name is a rough translation of the practice’s traditional idea that the swishing action “pulls” unwanted material out of the mouth. Nothing is swallowed; the oil is meant to be worked around and then discarded.

A typical modern routine looks like this:

• Take about one tablespoon (roughly 10–15 mL) of oil first thing in the morning, before eating or drinking.
• Swish gently and steadily for several minutes — many traditional and popular protocols suggest up to 15 to 20 minutes, though the studies that have tested it often used shorter times.
• Keep the motion relaxed. Vigorous swishing for a long time can tire the jaw and cheeks, which is one reason many people cut the time short.
• Spit the used oil into a trash can or paper towel — not the sink or toilet, because oil can congeal and clog pipes.
• Rinse with water, then brush and floss as usual.

The oil is spat out and never swallowed, because by the end it holds saliva, food debris, and oral microbes. It is important to understand that even in the studies where it helped a little, oil pulling was tested as an addition to normal hygiene or against a mouthwash — not as a stand-alone replacement for brushing and flossing.

Ayurvedic Origins: Kavala and Gandusha

Oil pulling comes from Ayurveda, the traditional system of medicine of the Indian subcontinent, where oil-based mouth care is described under two related terms. In gandusha, the mouth is filled completely with oil, held nearly still, and then released. In kavala (sometimes written kavala graha), a smaller amount is taken and actively swished or gargled. The modern “oil pulling” that circulates online is closest to kavala.

Classical Ayurvedic texts recommended these practices as part of daily self-care (dinacharya) and attributed to them a long list of benefits — stronger teeth and jaws, a clearer voice, relief from dry mouth and cracked lips, and general oral freshness. Sesame oil was the traditional oil of choice in much of this literature. It is fair and respectful to note that these were practical observations from a pre-microbiology era, offered as part of a whole lifestyle system. They are the historical root of the practice, but they are not clinical evidence, and it would be a mistake to treat centuries-old recommendations as if they had been tested the way a modern drug is. The honest question for today is a narrower one: when researchers actually measure plaque, gum inflammation, and bacteria, does oil pulling do anything?

How Coconut, Sesame, and Sunflower Oils Compare

Three oils dominate both tradition and research. They differ in taste, texture, and chemistry, and each has its advocates.

Sesame oil

Sesame oil is the classical Ayurvedic choice and the oil used in several of the earliest modern studies. It contains antioxidant compounds such as sesamol and sesamin. It has a distinct nutty flavor that some people find pleasant and others do not.

Coconut oil

Coconut oil is the most popular choice today, largely because of its mild taste and because it is rich in a medium-chain fatty acid called lauric acid, which has antimicrobial activity in laboratory settings. Most of the recent oil-pulling trials have used coconut oil. One practical quirk: coconut oil is solid at cooler room temperatures, so it needs a few seconds of swishing to melt in the mouth.

Sunflower oil

Sunflower oil appears in the older research too, often as a comparison oil alongside sesame. It is inexpensive and neutral-tasting.

Here is the honest part: no high-quality study has clearly shown one oil to be meaningfully better than another for oral health. Coconut oil is the most studied simply because it became the most fashionable, not because it was proven superior head-to-head. For people who try oil pulling, the “best” oil is mostly the one they find tolerable enough to use consistently. Both the tradition and the trials use ordinary edible (food-grade) oils.

What the Evidence Actually Shows

This is the heart of the matter, so it deserves a careful, honest look. There are real randomized studies of oil pulling, and several of them did report improvements. But the improvements need to be read alongside the serious limitations of the studies.

What the studies found

• Plaque and gingivitis: Small trials, several from the same research group in India, reported that daily oil pulling reduced plaque scores and signs of gum inflammation over two to four weeks compared with a person’s starting point.
• Bacteria: Some trials measured a drop in Streptococcus mutans, a bacterium tied to tooth decay, in plaque and saliva after a period of oil pulling.
• Bad breath (halitosis): A small pilot trial reported reductions in the microorganisms associated with mouth odor.

The limits of those findings

When independent reviewers pooled and appraised these studies, they consistently reached a sober conclusion: the research is weak. The main problems are:

• Small and short. Most trials enrolled only a few dozen participants and ran for a few weeks. Small, brief studies easily produce results that do not hold up.
• High risk of bias. Blinding is hard — you can taste and feel oil in your mouth — and many trials had methodological weaknesses. Several came from the same small circle of investigators.
• Improvement over baseline is not the same as being useful. Doing almost any focused oral routine tends to improve numbers a bit, partly because people who are being watched brush more carefully (the “Hawthorne effect”).
• Rarely better than the standard. When oil pulling was compared against chlorhexidine, the well-established antiseptic mouthwash, it was generally not superior; chlorhexidine matched or outperformed it. And no study shows oil pulling beating simple, correct brushing with fluoride toothpaste.

A 2020 systematic review of coconut-oil pulling (Woolley and colleagues; four randomized trials with 182 people, lasting 7 to 14 days) found significant reductions in salivary bacterial counts and plaque scores. It concluded that the limited evidence suggests coconut-oil pulling “may have a beneficial effect” on oral health and dental hygiene, as a possible add-on to normal care, while judging the data insufficient for conclusive findings and the risk of bias high. So the fair summary is not “it does nothing” and not “it works”; it is: the signal is small, the studies are shaky, and nothing suggests it can replace proven dental care.

How It Might Work: Proposed Mechanisms

If oil pulling does anything at all, researchers have proposed a few plausible ways it could nudge oral bacteria and plaque, though none is firmly proven.

• Mechanical action. Swishing any liquid vigorously for several minutes physically loosens and washes away food debris and loosely attached plaque, much like a long rinse would. Part of any benefit may simply be the swishing, not the oil itself.
• Saponification (a soap-like effect). Alkaline conditions and enzymes in the mouth can partly turn fats into soap-like substances. The idea is that these could help emulsify and lift away the sticky bacterial film. One in-vitro study from the practice’s proponents explored this, but it remains a hypothesis.
• A possible antimicrobial contribution. Coconut oil is high in lauric acid, which can inhibit some bacteria in the lab. Whether enough activity survives the brief, diluted, saliva-mixed conditions of real oil pulling to matter clinically is unknown.
• Reduced bacterial adhesion. A thin oily coating might make it slightly harder for microbes to stick to tooth surfaces, though this is speculative.

The key takeaway on mechanism: these are reasonable ideas, mostly supported by test-tube work rather than by strong evidence in people’s mouths. A believable mechanism is not proof of a meaningful benefit.

The Debunked Claims

Oil pulling’s biggest problem is not the practice itself — it is the exaggerated marketing wrapped around it. Several widely repeated claims have no scientific support, and it is worth naming them directly.

• “It detoxifies the body” / “pulls out toxins.” There is no evidence that swishing oil draws toxins, heavy metals, or systemic waste through the lining of the mouth. The body has organs for that job — the liver and kidneys. “Detox” here is a marketing word, not a measured effect.
• “It whitens teeth.” No good study shows oil pulling whitens teeth. Any impression of brightening is most likely from removing surface film, the same as a thorough rinse or brushing would do — not true whitening of the tooth.
• “It cures headaches, arthritis, asthma, diabetes, heart disease,” and other systemic illnesses. These claims trace back to popularized folk assertions, not to clinical trials. There is no reliable evidence that oil pulling treats any disease outside the mouth, and believing it does can be dangerous if it delays real treatment.
• “It replaces the dentist.” It does not. Oil pulling cannot repair a cavity, treat gum disease that has taken hold, or substitute for a professional cleaning.

Being skeptical of these claims is not being closed-minded — it is exactly the honesty the topic deserves. A gentle oral rinse is a modest thing; treating it as a cure-all does real harm by pulling people away from care that works.

The Real Safety Concern: Lipoid Pneumonia

For most healthy adults, swishing and spitting a food-grade oil is low-risk. But there is one genuine, documented harm that deserves respect: exogenous lipoid pneumonia. This is an inflammation of the lungs that can occur when oil droplets are accidentally breathed in (aspirated) instead of spat out. Because the practice involves holding a large amount of oil in the mouth for many minutes, sometimes while talking or moving around, small amounts can slip into the airway — especially if someone laughs, coughs, or is prone to swallowing problems.

This is not merely theoretical. Published case reports describe lipoid pneumonia in people who oil-pulled regularly, including cases linked to repeated sesame-oil pulling and a case of recurrent pneumonia tied to the habit. Lipoid pneumonia can cause cough, shortness of breath, and chest discomfort, and it can be slow to resolve.

What the aspiration risk means in practice:

• Swishing so hard or so long that the throat or jaw tires makes it easier to lose control of the oil.
• Lying down, talking, walking around, or being distracted while holding the oil makes it easier for some of it to slip into the airway.
• Young children, and anyone with swallowing difficulties or a high risk of aspiration, are the people most likely to breathe the oil in instead of spitting it out — and breathed-in oil is how lipoid pneumonia starts.
• The warning signs are breathing symptoms. In two reported cases linked to months of sesame-oil pulling (Kuroyama and colleagues, 2015), one person had a dry cough and the other shortness of breath; chest CT scans showed hazy “ground-glass” shadows, and oil-laden cells found in the lungs confirmed lipoid pneumonia. One improved after steroid treatment and a lung wash (bronchoalveolar lavage); the other needed no intensive treatment. A new cough or shortness of breath after starting oil pulling matches these reports, and trouble breathing is a warning sign that hospitals treat as urgent.

Other minor issues reported include jaw soreness from over-long swishing, upset stomach or diarrhea if oil is swallowed, and rarely allergic reactions to a particular oil.

Not a Substitute for the Basics

This point is important enough to stand on its own. Whatever oil pulling may or may not add, it has not been shown to take the place of the small set of habits that genuinely prevent tooth decay and gum disease:

• Brushing twice a day with fluoride toothpaste. Fluoride is one of the best-evidenced tools in all of medicine for preventing cavities. Nothing in oil pulling replaces it.
• Cleaning between the teeth daily with floss or interdental brushes, where a toothbrush cannot reach.
• Regular dental checkups and cleanings, which catch and treat problems oil pulling cannot touch.
• Limiting frequent sugary and acidic drinks and snacks, the true drivers of decay.

The danger is not that oil pulling is poison — it usually is not. The danger is that someone swaps a proven routine for an unproven one and quietly lets decay or gum disease advance. None of the studies tested oil pulling in place of brushing, flossing, or fluoride, and none shows it beating brushing with fluoride toothpaste.

How to Try It Safely as an Adjunct

For people who still want to try oil pulling — perhaps for the fresh-mouth feeling — the lower-risk way described below treats it as an extra on top of real care, not instead of it.

1. The basics come first. Brushing twice daily with fluoride toothpaste, cleaning between the teeth, and dental appointments stay the foundation; oil pulling is the optional add-on.
2. A clean, food-grade oil the person can tolerate — coconut, sesame, or sunflower are the usual choices.
3. A modest amount, about a tablespoon, usually on an empty stomach in the morning.
4. Gentle swishing. A few minutes of relaxed swishing is the usual amount; there is no proven advantage to pushing toward 20 minutes, and longer sessions raise the risk of fatigue and accidental aspiration.
5. The oil is spat out, not swallowed — into the trash or a paper towel rather than the sink or toilet, where it can clog drains.
6. Rinsing, then brushing and flossing, follow.
7. Problems reported with the practice are a cough or breathlessness (the lipoid-pneumonia warning signs described above, which hospitals treat as urgent), jaw pain, stomach upset, and allergic reactions.

Treated this way, oil pulling is a harmless little ritual for people who enjoy it, with modest expectations and fluoride toothpaste still in the routine.

The Honest Bottom Line

Oil pulling is an ancient practice with a small, shaky modern evidence base. At best, the research hints that swishing oil may slightly reduce plaque, gum inflammation, and cavity-linked bacteria — but the studies are small, short, and biased, and oil pulling has never been shown to outperform an ordinary antiseptic mouthwash, let alone brushing with fluoride. The popular claims that it “detoxes,” whitens teeth, or cures disease are not supported by evidence.

So the fair, non-promotional verdict is this: oil pulling is, at most, a harmless adjunct — not a substitute for the dental basics that actually work. If it appeals to you and you do it carefully, it is unlikely to hurt (with the real but rare exception of lipoid pneumonia if oil is inhaled). In the studies, oil pulling was tested as an addition to normal hygiene or against a mouthwash, not as a replacement for brushing, flossing, fluoride, and dental visits.
